ALSA: hda/realtek - Fix overflow of vol/sw check bitmap

commit c14c95f62ecb8710af14ae0d48e01991b70bb6f4 upstream.

The bitmap introduced in the commit [527e4d73: ALSA: hda/realtek - Fix
missing volume controls with ALC260] is too narrow for some codecs,
which may have more NIDs than 0x20, thus it may overflow the bitmap
array on them.

Just double the number to cover all and also add a sanity-check code
to be safer.
